ARTHUR C. WOOD, OF MANSFIELD, OHIO, ASSIGNGB- TO THE OHIO BRASS COMPANY, OF

MANSFIELD, OHIO, A CORPORATION OF NEW' JERSEY.

CONDUCTOR snrronr.

Application `riled December 6, 1922. Seria] No. 605,266.

To all whom t may concer/n Be it known that I, ARTHUR C. WOOD, a citizen of the United States of America, residing at Mansiield, 'in `the county of Richland and Sta-te of Ohio, have invented certain new and useful Improvements in Conductor Supports, of which the following is a specification.

My invention relates to supportsfor conductors and particularly `that class of support by means of which the conductor may be gripped and secured to a hanger.

The object of my invention is to produce a cheap, simple, eiiicient device which can be easily secured to the conductor and hanger and easily removed therefrom.

May invention resides in the new and novel construction, arrangement and combination of the various elements more fully hereinafter described andshown inthe/drawings.

Tn the drawings:

Fig. 1 is a view in elevation ofa device embodying my invention secured to a conductor.

vFig. 2 is an end view Fig. l.

Fig. 3 is a transverse sectional viewof Fig. l on the line 3-3.

Fig. 4 is a longitudinal sectional view taken n the line 4-4 of Fig. 2.

Fig. 5 'is a transverse sectional view of Fig. l with the exception that` the device is shown secured toa hanger H and the jaws opened up to receive a conductor C.

' Fig. 6 is a horizontal sectional view taken on the line 6 6 of Fig. 3.

InA the preferred form of device embodying my invention I employ a supporting member l provided with a threaded recess 2 by means of which the device may be secured to the stud of a hanger H. At the lower end of the member l is a horizontal projecting ange 3. Rotatably mounted upon the' supporting member l and held against lateral movement in one direction by the flange 3 is a member 4 provided with polygonal faces F arranged for the application of a wrench or other means lfor operating the rotatable member 4. Engaging with andsupported by the member 4 is a connecting member y5 having a threaded engagement 6 with the member 45. Theconnecting member 5 is' recessed and within the recess are-'mounteda pair of jaws 7 provided at in elevation of their lower ends with lips 8 to engage the conductor C. The distance A between the adjacent faces of the jaws 7-7 is suiiiciently great to permit the jaws to be entered through the lower opening into the recess 9 of the member 5.

To retain the jaws within the recess 9 l provide two lugs l0 projecting from the lower end of the member l and spaced apart and which provide a transverse channel ll therebetween. The lugs l0 projecting withinfthe space between the upper ends of the jaws engage therewith and prevent the jaws moving together a sufficient yamount to fall out of the member 5 as the jaws are not capable of mo\*ing toward each other at the upper end a suioient distance to pass through the lower Opening in the member 5. Projecting inwardly from diametrically opposite points at the upper end of each jaw is a lug 12 positioned within the channel ll and this arrangement interlocks the supporting member l and the jaws against relative rotation. This permits the clamp to be secured to the hanger by gripping the jaws with the hand or a wrench and rotating the same, which in turn rotates the member l into engagement with the hanger H. Projecting inwardly and at diametrically opposite points of the member 5, and withinthe recess are narrow lugs 13 which engage with the adjacent inner faces of the jaws at their upper end' and prevent relative rotation of the jaws with respect to the connecting member 5.

This construction permits the jaws and connecting member to not only pivot relatively to each other about the point of engagement 14, but t0 also have a sliding engagement at this point relative to each other. The upper and outer edges l5 of the jaws 7 are arranged to engage with the flange 3.

` To `install my device upon a hanger and conductor, the device is iirst secured to a hanger stud H by gripping the jaws by means of the hands and rotating the member l into position upon the hanger stud. This is possible through the rfact that the jaws and member l'are interlocked as described or the member 5 may be rotated and the member l secured into position upon the hanger lstud for the reason th-atthe,

member 5 is interlocked with the jaws and the jaws in turn interloclred with the member l. lf the jaws are not suiiiciently open llO to receive theconductor the member 4 is rotated in the proper direction to permit the member 5 to move downward. This will permit the aws to slide apart as shown in Fig. 5. After introducing the conductor in position between the lips 8 8 the member 4 is rotated in the opposite direction thereby drawing the member 5 upward and the jaws simultaneously therewith, and this movement after it is completed will force the jaws to pivot and also slide about their point of engagement l14 with the member 5 due to the engagement of the jaws with the liange 3 and the tapered Jface 16 on the exterior upper end of each jaw. This rotation of the member 4 can be made by means of the hand until the lips 8 engage the conductor after which a wrench applied to the faces F of themember 4 will bring the r jaws into further secure engagement with the conductor.

it will be evident to one skilled in theart that there are modiiications which may be made in the construction herein disclosed, but which will fall within the scope of my invention, therefore, I do not wish to be limited other than by my claims.
